这项研究调查了在面部运动中被认为是静止的面部点的三维位移。目前，这些点用于评估正常面部运动和面神经麻痹后的治疗干预时测量运动面部区域的位移。然而，尚不清楚这些地方是否为“静止”点。采用专家视觉运动分析系统对42名正常受试者的面部运动数据进行采集和分析。面部表情时没有发现任何一个点是静止的。然而，对于每个单独的表情，有几个点的动作非常小。这些被称为“参考”点。这些微小的运动可能是系统噪声、生理性震颤、皮肤运动或面部表情时的头部运动的结果。未来对正常受试者和面神经麻痹患者面部运动过程中标记点位移的研究可以考虑“参考”点位移对整体面部运动的贡献。
This study investigated the 3-dimensional displacement of points on the face that were thought to be still during facial movement. These points are currently used to measure displacement of moving facial regions during assessment of normal facial movement and treatment interventions following facial nerve paralysis. It is, however, unknown if these places are "still" points. The Expert Vision Motion Analysis System was used to collect and analyze data on 42 normal subjects during facial movement. No point on the face was found to be still during facial expression. However, several points were present with very small movements for each individual expression. These were termed "reference" points. These small movements may be the result of system noise, physiological tremor, skin movement, or head-holder movement during facial expressions. Future studies of the displacement of the markers during facial movement in both normal subjects and patients with facial nerve paralysis may take into account the contribution of the "reference" point displacements to the overall facial movement.
